New Nook Glowlight 4?

[jvscholz]

Ok, good news. Using "fastboot flash boot nnglow21.img"and "fastboot reboot" I was able to get it into recovery successfully. This time "update-binary 2 1 /data/media/0/update.zip" worked and the device rebooted as expected. I didn't have to create recovery in /cache as it already existed. Upon setting up the device it immediately started updating to 8.1.4.45 and now it appears as if the device is back to oem as it's no longer rooted (assuming it was rooted in the first place, I couldn't check in time). Should I reattempt to root the device? I had assumed that the latest update was already installed and that it would be safe to connect to wifi. thank you

Oh, good.
Wasn't the update.zip that you used already the 45 version that I posted the link?
Why would it update after booting normal system?

In any case, you've seen that they make it almost impossible to get to "recovery".
The stock "recovery" is only "flash factory".

Edit: Certanly you can Magisk.
I just used the boot.img extracted directly out of the 45 update.zip
You can Magisk convert it then either "fastboot flash" or recovery & dd or like I did, just dd it in the rooted UART console.

The default "sleep" images are in /system/media/SleepImageNook.
The files are called 1.png to 6.png
If you are using Magisk you can write a module to overlay those files.
They are obviously 1072 x 1448 PNG images.

If you don't like Magisk you can flash neoglow21.img (in my sig) to recovery.
Then you can mount system and delete 2.png to 6.png and replace 1.png

mount -t ext4 /dev/block/mmcblk0p5 /system
cp whatever.png /system/media/SleepImageNook/1.png
reboot

I wonder when its coming out?

Is it necessary for update.zip in the rooting procedure to match the exact version of the nook firmware onboard? I assumed this, but in my case I could not update from the listed 8.1.4.43(A) to (hopefully) match the mentioned 8.1.4.45 update. I also tried to predict the url based on the mentioned examples, but both /4.43/ and /4.43A/ variants didn't work.
Thanks

Interestingly trying to work around the inability of my nook to upgrade over the air (see my previous post), discovered that the old way of manual update listed at this page kind of works on glowlight 4. So if I connect the device to the PC and copy update.zip file into to root of the storage drive then after disconnecting and about 50 seconds, Nook unexpectedly restarts and tries to upgrade the system. The only problem in my case was that the 8.1.4.43(A)->8.1.4.45 (downloaded from the link posted several times here and with https proto just in case) doesn't work with an error "Install failed'. It restores to the previous state, but mission was not complete unfortunately...

EDIT:
Don't know what I did, may be reformat mmcblk0p1 with mkfs?
After re-flashing neo noogie and misc-rec, and several reboots, it now works and I have successfully updated GL4, it is now back to factory again.
Thank you for the wonderful Neo Noogie.
Please disregard the rest of the reply.

Hi Renate,

I have done something wrong to my GL4 and it is now totally blank. I managed to flash neo noogie and misc rec.
However, when booting into recovery, I did not see the Neo Noogie splash.
I can access adb and when installing update, UDISK is missing.

E60P54_android:/cache # mount -t t2fs /dev/block/by-name/UDISK /data                                                               
mount: '/dev/block/by-name/UDISK'->'/data': No such device

I can mount cache (mmcblk0p9), but I can not mount data (mmcblk0p1)
Is there any way to create this partition and proceed with the update installation?

Many thanks!

If something doesn't react as portrayed, stop!

Preparation

Download http://su.barnesandnoble.com/nook/pi...1/gentoo/3.123

Download nnglow21.img from http://www.temblast.com/neonoogie.htm

Get misc-rec.prc from attachment. Just rename it plain misc-rec

Install rooted recovery

Go to fastboot:

C:\>fastboot flash recovery nnglow21.img
C:\>fastboot flash misc misc-rec

Long power press to reset, you should see a splash with "Neo Noogie".

Install update

C:\>adb shell
# mount -t f2fs /dev/block/by-name/UDISK /data
# mount -t ext4 /dev/block/by-name/cache /cache
# ^D
C:\>adb push update.zip /data/media/0
C:\>adb shell
# update-binary 2 1 /data/media/0/update.zip
<lots of printing, should end happily>
# dd if=/dev/zero of=/dev/block/by-name/misc
dd: /dev/block/by-name/misc: write error: No space left on device <not a problem, correct>

^D is control key + d

Hit the power button (which has "Reboot normally" written under it)
If that doesn't work do a really long power press ~30 seconds.

return {
[139] = "LPgBack", -- Nook Left Page Back (left lower button)
[140] = "LPgFwd", -- Nook Left Page Forward (left upper button)
[141] = "LPgFwd", -- Nook Right Page Forward (right upper button)
[142] = "LPgBack", -- Nook Right Page Back (right lower button)
}

This method stopped working recently. May be something to do with firmware update. Any ideas how to put the page turn buttons back to work on Koreader? Thanks.
